Bun-suitable garden shrubs and plants

Hi everyone,

I'm hugely extending Ham and Bea's outdoor pen (so it's all big and lovely for when Plumpkin is well enough to live with them!) - right now it's just lawn but I want to plant shrubs, bushes and other plants that they can play in and lie under for shade.

Can anyone recommend plants that aren't poisonous to bunnies, but also that they won't eat in 5 seconds? I'm keen on having some large shrubs to give height to the space that they can play under and hide in.

There will be a gate with a metal arch into the run, so I'd also like to grow a climber over the arch which is once again bunny friendly.
